The thought of Spinoza is divided into two main streams. One, through his Ethica, presents ontology, epistemology, the theory of sentiment and ethics; the other develops theology and political philosophy preponderantly in Tractatus Theologico-Politicus and Tractatus politicus. This study elucidates Spinoza’s political philosophy, focusing on the relationship between the individual and the government exposed in Tractatus Theologico-Politicus. It is the salient subject how the personal freedom and the government power are related mutually. One republic could go to the way of either the prosperity or the ruin according to the nature of this relationship. Spinoza articulates the individual freedom and the political obedience to harmonize them, especially studying the tripartite association of philosophy, religion and politics. First, he acquires against the ecclesiastical authority the freedom of philosophy and religious belief by separating reason from religion. However as the personal freedom has to be in harmony with the political organization, he determines the principle of the government formation and then, to the government power, subjugates the legal rights related to the expression of thought and the praxis of faith. This perspective that subjects all individual expression to the government power consequently inheres the danger of despotism and totalitarianism. He finally reaches the point that the dictatorial oppression on the individual thought and faith is viciously harmful to the safety and peace of the republic, and thus, he suggests the pragmatic theory of tolerance that the government must guarantee the freedom of the expression and religion.
